In contrast to the above, in other domains, such as location-privacy, the focus is usually on optimizing the QoS, i.e., the utility from the point of view of the user. Notably, this is the case for the framework proposed by Shokri et al. [1]}, [2]}, and
for geo-indistinguishability [3]}, a variant of LDP that takes into account the distance between locations [4]}, [5]}. The preservation of the best possible quality of service despite the obfuscation operated on the data is what motivates these efforts.
